Subject: wg syncconf (and setconf) error when one or more endpoints is unresolvable
Date: Tue, 15 Jun 2021 04:35:43 -0400
Message-ID: <> (raw)


Assume a tunnel with say 3 peers. Peer A is accessible via an IPv4
address, Peer B by some FQDN, and Peer C by some other FQDN. Let's
also assume that Peer C was misconfigured with an unresolvable FQDN.
wg syncconf (and setconf) fails with 'Name does not
resolve...Configuration parsing error'

Is it expected behavior in this case that *none* of the peer
configurations are actually applied? It seems like a more appropriate
behavior would be to go ahead and configure the remaining peers (Peer
A + B) but only fail on the peer with an unresolvable endpoint (Peer
C). It of course is completely possible to re-implement syncconf and
setconf using explicit `wg set` calls as a workaround.

Am I missing something here?
